1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

The current study explored whether specific mechanisms of moral disengagement predicted bullying perpetration from a sample of upper elementary school students in Sweden. The study hypothesized that both moral justification (portraying harmful actions as serving a noble or socially valuable purpose) and victim attribution (blaming the victims for their own suffering) would be positively associated with subsequent bullying perpetration. Participants, who consisted of 471 students in grades 4-6, completed a web-based questionnaire at two timepoints. Analyses included two linear regression analyses-one with indirect bullying and one with direct bullying. Results indicated that moral justification significantly predicted bullying. The victim attribution predicted higher levels of indirect bullying and was significantly associated with bullying among girls. The findings suggest that assessing students' morals and identifying and intervening in disengagement patterns might potentially be avenues practitioners need to consider. Also, programs need to consider gender differences and specifically target victim-blaming attitudes.
